I run 75 Micron MESH.
swapped out every three days. I run two at a time
I hand wash them then soak with a capful of bleach in a 1L jug with two socks. Rinse them with lots hot water two days later and they are as clean as they were when they were new.
my sump is spotless...its the first thing reefers mention when they see my setup - how clean my sump is... must mean my display looks like $h!t
